"Radaufhängung""Wheel suspension"
Die Erfindung betrifft eine Radaufhängung für in den Fahrzeugkörper einschwenkbare Räder bzw. Radachsen. Solche einschwenkbaren Radanordnungen sind zum Beispiel bei Amphibienfahrzeugen notwendig. Wenn diese von Land- auf Wasserfahrt übergehen, müssen die Räder zur Verringerung des Wasserwiderstandes und zur Verbesserung der Steuerfähigkeit im Wasser eingezogen werden. Ähnliches gilt bei Landfahrzeugen, die im Rahmen ihres Einsatzes fest auf dem Boden abgesetzt werden müssen. Zur Beherrschung des Ein- und Ausschwenkvorganges, insbesondere zur Fixierung der beiden Endlagen, waren bisher sehr aufwendige Schwingensysteme erforderlich.The invention relates to a wheel suspension for wheels or wheel axles that can be pivoted into the vehicle body. Such Swivel-in wheel arrangements are necessary, for example, in amphibious vehicles. If this from land to Passing water travel, the wheels must reduce the water resistance and improve the controllability be absorbed in the water. The same applies to land vehicles that are permanently on the Need to be deposited on the ground. To control the swiveling in and out process, in particular to fix the two End positions, very complex swing systems were previously required.
Der Erfindung liegt die Aufgabe zugrunde, diese aufwendigen Konstruktionen zu vermeiden, wobei trotzdem sichergestellt werden muß, daß die Räder bzw. die Achsen auch dann in ihrer jeweiligen Endstellung verbleiben, wenn einmal der hydraulische Schwenkzylinder ausfallen sollte.The invention is based on the object of avoiding these complex constructions while ensuring that they are nonetheless must be that the wheels or the axles remain in their respective end positions even if the hydraulic swivel cylinders should fail.
Die Erfindung löst diese Aufgabe durch eine Radaufhängung mit einem Lenkhebelparallelogramm zur Sicherung der senkrechten Lage der Achse dergestalt, daß ein um einen zwischen hydraulischem Schwenkzylinder und Anlenkpunkt an der Achskonstruktion angeordneten Drehpunkt verschwenkbarer, schwach gekröpfter Winkelhebel vorgesehen ist.The invention solves this problem by a wheel suspension with a steering lever parallelogram to secure the vertical position of the axis such that a between a hydraulic pivot cylinder and pivot point on the Axis construction arranged pivot point pivotable, slightly cranked angle lever is provided.
Die Verstellkinematik ist so ausgelegt, daß sowohl in ausgefahrener, als auch in eingefahrener Stellung der Radachse durch geringfügiges Überschreiten des Totpunktes am Winkelhebel das Lastmoment den Verstellzylinder jeweils gegen den mechanischen Endanschlag beansprucht. Dadurch ist sichergestellt, daß auch bei Ausfall der Hydraulik die jeweils gewählte Radstellung beibehalten wird.The adjustment kinematics is designed in such a way that the wheel axle is in the extended as well as in the retracted position by slightly exceeding the dead center on the angle lever, the load torque counteracts the adjusting cylinder the mechanical end stop is claimed. This ensures that even if the hydraulic system fails, the respective selected wheel position is retained.
Weitere Merkmale der Erfindung und Einzelheiten der durch dieselbe erzielten Vorteile ergeben sich aus der nachfolgenden Beschreibung einer in den beigefügten Zeichnungen rein beispielsweise und schematisch dargestellten Ausführungsform des Erfindungsgegenstandes. Further features of the invention and details of the advantages achieved by the same emerge from the following Description of an embodiment of the subject matter of the invention shown purely by way of example and schematically in the accompanying drawings.
Fig. 1 zeigt einen Achsbereich eines Fahrzeuges mit ausgefahrener Achsanordnung in Straßenfahrtsteilung, inFig. 1 shows an axle area of a vehicle with extended axle arrangement in road travel division, in
Fig. 2 ist derselbe Bereich mit eingefahrener Achsanordnung wiedergegeben.Fig. 2 shows the same area with the retracted axle arrangement.
Der Fahrzeugkörper 1 des Radfahrzeuges bzw. der Schwimmkörper eines Amphibienfahrzeuges weist Radkästen 2 auf, in welche die Räder 3 eingezogen werden können. Zwischen den beiden Radkästen 2 weist der Fahrzeugkörper 1 noch eine quer durchgehende Ausnehmung 4 für die Achse und die an dieser vorgesehenen Teile auf.The vehicle body 1 of the wheeled vehicle or the floating body of an amphibious vehicle has wheel arches 2 on, in which the wheels 3 can be drawn. The vehicle body 1 has between the two wheel housings 2 nor a transversely continuous recess 4 for the axis and the parts provided on this.
Die Fahrzeugachse 5 ist in an sich bekannter Weise an zwei parallel verlaufenden Lenkhebeln 6 und 7 aufgehängt, die die senkrechte Ausrichtung der Achse bei jeder Lage, die sie einnimmt, sicherstellen.The vehicle axle 5 is suspended in a manner known per se on two parallel steering levers 6 and 7, which ensure the vertical alignment of the axis in every position it assumes.
Die Kolbenstange 8 des hydraulischen SchwenkZylinders 9 bewegt einen schwach gekröpften Winkelhebel 10 mit zwei Hebelarmen 11 und 12, der um einen Drehpunkt 13 schwenkbar ist.The piston rod 8 of the hydraulic swivel cylinder 9 moves a slightly cranked angle lever 10 with two lever arms 11 and 12, which can be pivoted about a pivot point 13 is.
An dem einen Hebelarm 11 ist das freie Ende der Kolbenstange 8 angelenkt, der andere Hebelarm 12 des Hebels 10 ist gelenkig mit der Achse 5, beim dargestellten Beispiel mit einem zwischengeschalteten Federbein mit Stoßdämpfer 14, verbunden. Eine Kardanwelle 15 ist lediglich strichpunktiert angedeutet.The free end of the piston rod is on one lever arm 11 8 articulated, the other lever arm 12 of the lever 10 is articulated with the axis 5, in the example shown an intermediate strut with shock absorber 14 connected. A cardan shaft 15 is only shown in dash-dotted lines indicated.
Bei ausfahrendem Schwenkzylinder 9 wird die ganze Achsund Radanordnung über den Winkelhebel 10 nach unten aus dem Radkasten 2 herausgedrückt. Dabei überschreitet der Hebel 12 um den Winkel β den unteren Totpunkt geringfügig. Der Drehsinn des Lastmomentes wird umgekehrt. Der Schwenkzylinder 9 wird nun durch das Lastmoment in Richtung Ausfahren, d.h. gegen die mechanische Endstellung belastet. Durch diese Umkehrung der Kraftrichtung ist die ganze Anordnung in dieser Lage gesichert. Dies gilt auch dann noch, wenn durch irgendeinen Schaden der Schwenkzylinder 9 seine Druckflüssigkeit verlieren sollte.When the swivel cylinder 9 extends, the entire axle and wheel arrangement is pushed downward out of the wheel arch 2 via the angle lever 10. The lever 12 slightly exceeds the bottom dead center by the angle β. The direction of rotation of the load torque is reversed. The swivel cylinder 9 is now loaded by the load moment in the direction of extension, ie against the mechanical end position. By reversing the direction of force, the entire arrangement is secured in this position. This also applies if the swivel cylinder 9 should lose its pressure fluid due to any damage.
Auch bei eingefahrener Radachse wird bei Erreichen des Anschlages im Schwenkzylinder 9 eine stabile Endlage erreicht. In dieser Stellung wird der Zylinder 9 durch das Lastmoment in Richtung Einfahren, ebenfalls gegen eine mechanische Endstellung belastet. Auch diese Radstellung wird bei einem eventuellen Ausfall der Hydraulik stabil beibehalten.Even with the wheel axle retracted, when the Stop in the swivel cylinder 9 reaches a stable end position. In this position, the cylinder 9 is due to the load torque in the retracting direction, also loaded against a mechanical end position. This wheel position is also used in a possible failure of the hydraulic system.
